CONNECTING-ROD FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 635,306, dated October24, 1899. Application filed July 14, 1898. Serial No. 686,939. (Nomodel.)

To all whom it may concern.-

Be it known that I, FRANK J. DYETT, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Connecting-Rods forType- WVriters; and I do hereby declare the follow-. ing to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to an improvement in rods for connecting thekey-levers and typebars of type-writers and similar machines.

The object of the invention is to employ a minimum amount of metal, toprovide a rod of one continuous piece of metal, and to provide means forretaining the rod in position in the eye of the type-bar.

My invention consists in the novel construction and combination of partshereinafter described and claimed, and illustrated in the accompanyingdrawings, in which- Figure 1 is a perspective view of the connecting-rodattached to a section of a typebar. Fig. 2 is a front elevation of therod. Figs. 3 and 4 are side elevations. Fig. 5 is a vertical transversesection through the upper portion of the device on line 5 5 of Fig. 2.Fig. 6 is a View of the spring and rod detached. Fig. 7 is a lower endview of said spring, and Fig. 8 is a view of the springblank.

Referring to said figures by letters of reference, A is the threaded endof the rod A and is preferably of greater diameter than the remainder ofthe rod, which is diminished in diameter from a point above the thread,so as to reduce the quantity of metal in the rod, and thereby reduce theweight thereof. Ata desired point 13 near the upper end of the de vicethe rod is bent back at a slight angle and then forward again into ahook O, which is preferably curved downwardly at the extreme end, asshown at c in the drawings. The center of the hooked end 0 is locateddirectly above the straight intermediate portion of the rod A, so as topermit a direct pull thereupon. v

Although the end 0 tends to hold the typebar in the center of the hook Cat all times, I provide means for retaining the same in position whichare extremely simple,-though effective. This consists of a strip ofpreferably thin sheet-steel cut out in substantially the shape shown inFig. 8. The edges of the lower portion 61 thereof are turned up, makingthe same approximately arc-shaped in cross-section. This portion at issprung over or clamped upon the rod A at and below the point B, claspingthe same tightly, as is obvious. slightly toward the end, bears normallyagainst the end of hook G. In order to prevent the spring D fromslipping upon the rod A, it is preferably soldered thereto, although itcould be attached equally as well in other ways, as by indenting thesame.

The connecting-rod is readily attached to the type-bar by pressing backspring D and inserting hook 0 into the eye of the type-bar. Uponremoving pressure the spring will immediately spring back against thehook and retain the bar in its proper position. The downwardly-curvedend 0 of the hook guides the type-bar to the center of said hook, whichis at a point directly over said bar, and as a result a direct downwardpull in a line with the longitudinal axis of said rod is obtained.

As the rod is of but one piece from keylever to type-bar, no troublewill result from the disconnection of parts resulting from the jointsbecoming loose, and as no strain is exerted upon the spring D, exceptingwhile attaching or detaching the device, the stability of the devicewill be readily appreciated.

In the foregoing description I have shown the preferred form of myinvention; butI do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit or.sacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.

Having thus described my invention, what I therefore claim as new, anddesire to secure by Letters Patent thereon, is V 1. A connecting-rod fortype-writers, consisting of a rod, a recurved hook formed at one end ofsaid rod, the center of said hook being directly above the intermediateportion of the rod, and a spring-strip having its inner end portionsubstantially arc-shaped in cross-section and clasping, and rigidlysecured The upper fiat part D, which tapersto, said rod, its other endportion normally resting against the end of said hook, substantially asdescribed.

2. A conneeting-rod for type-writers, e011- sisting of a rod having oneend and its intermediate portion reduced, a recurved hook formed at thered uced end of said rod, the center of said hook being directly abovethe intermediate portion of the rod, and a spring-strip having its innerend portion substantially arc-shapcd in cross-section and clasping, andrigidly secured to, said rod, its other end portion normally restingagainst the end of said hook, substantially as described.

3. A connecting-rod for type-writers, consisting of a rod, a reducedintermediate and end portion, an inwardly-curved hook formed by thereduced end of said red, the center of said curve being on a line withthe intermediate portion of the rod, and a spring-strip rigidly securedto said rod and having one inner end portion substantially are-shaped incross-section and clasping, and rigidly secured to, said rod, its otherend portion normally resting against the end of said hook,suhstantially'as described.

In testimony whereof I affix my signature in presence of two Witnesses.

FRANK J. DYET".
